Neuroimaging studies help to diagnose cerebral visual impairment in children

Neuroimaging studies and visual field testing can help prevent a delayed diagnosis of mild cerebral visual impairment in children, a study found.
Scott Lambert, MD, and colleagues at Emory University reviewed the medical charts of seven patients, aged 2 to 10 years, who had delayed diagnosis of cerebral visual impairment. Visual acuity ranged from 20/40 to 20/400; visual fields ranged from full to homonymous hemianopias.
A pediatric neuroradiologist evaluated the patients' neuroimaging charts. Findings ranged from "subtle occipital lobe abnormalities to obvious cerebral volume loss," the authors said.
The authors concluded that mild cases of cerebral visual impairment can be cryptic, and that neuroimaging studies and visual field testing can help differentiate these cases from other conditions.
The study was published in the August 2006 issue of the British Journal of Ophthalmology.
